I just bought a 2016 sportsman 450 ho, the quad is almost brand new, only 1500 km on it. It ran great for a few days. We had a cold snap, minus 40 Celsius to be exact. Went to start it, it started just fine, sputtered a bit and died within a few seconds. Would continue to turn over, but would not start. It did start for about 5 seconds the next day, backfired and didn't run again. 3 days later and a fresh charge on the battery and it ran for a few seconds again, then died. Figured I would get a new battery, had to be the issue. Bought a new battery, charged it up to capacity. Installed it, and here we are, it wont start just keeps turning over. It has fresh gas, good spark plug. I have no idea where to go from here. (Note, lights and winch work no problem when quad is on).
